what are the components of the human heart?
Answers
Answer:
The heart consists of four chambers:
Atria: the two upper chambers (they receive blood).
Ventricles: the two lower chambers (they discharge blood).
The left atria and left ventricle are separated from the right atria and right ventricle by a wall of muscle called the septum.
The wall of the heart consists of three layers of tissue:
Epicardium — protective layer mostly made of connective tissue.
Myocardium — the muscles of the heart.
Endocardium — lines the inside of the heart and protects the valves and chambers.
These layers are covered in a thin protective coating called the pericardium.
Right side
The right atrium receives deoxygenated blood from the body through veins called the superior and inferior vena cava (the largest veins in the body).
The right atrium contracts and blood passes to the right ventricle.
Once the right ventricle is full, it contracts and pumps the blood through to the lungs via the pulmonary artery, where it picks up oxygen and offloads carbon dioxide.
Left side
Newly oxygenated blood returns to the left atrium via the pulmonary vein.
The left atrium contracts, pushing blood into the left ventricle.
Once the left ventricle is full, it contracts and pushes the blood back out to the body via the aorta.
